Are you sure it's bacterial overgrowth and not fungal? You can't "test" for fungus,(Won't show up on a report from your doctor).Symptoms may include bloating, digestive trouble, "hung over" feeling, brain fog, memory loss, skin problems, FM, chronic fatigue, anxiety, blah, blah, blah... Have you considered an antifungal diet/natural supplements for awhile to see if your symptoms clear up, or even get better?
